把高频词及其可视化呈现作为数字图书馆用户信息分析的辅助策略,对其与用户信息分析效率之间的关系进行考察,通过对照两组用户三个阶段的实验结果,发现高频词表对被试完成浏览型的数字信息分析任务的效率无显著影响;高频词的可视化呈现对被试完成浏览型数字信息分析任务的效率有显著影响;高频词及其可视化呈现对被试完成归类型数字信息分析任务的效率无影响。实验结果证明了数字图书馆辅助用户提高信息分析效率的可行性。
The high-frequency words and their visual presentation as an auxiliary strategy for the analysis of users’ information in digital library, and the relationship between the high frequency words and user information analysis efficiency are investigated. By comparing the experimental results of three phases of two groups of users, The visualization of high-frequency words had a significant effect on the efficiency of the subjects in completing the task of viewing digital information analysis. The high frequency words and their visualization showed that they were able to complete the task of reading the digital information effectively. The efficiency of the typed digital information analysis task has no effect. The experimental results prove the feasibility of digital library assisting users to improve the efficiency of information analysis.
